Finished stole being passed (8)
I believe the answer is:
overtook
'being passed' is the definition.
(I've seen this in another clue)
'finished stole' is the wordplay.
'finished' becomes 'over' (over can mean finished or ended).
'stole' becomes 'took' (I've seen this in another clue).
'over'+'took'='OVERTOOK'
(Other definitions for overtook that I've seen before include "Caught up with and went past" , "Caught unprepared" , "having gone to right" , "Caught up with and passed" .)
